LUBRICATING MEANS FOR TWIST'ER RINGS.

Application filed June 3,

To all whom it may concern:

Be it known that I, DONIGAN i). 'lowens. citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in Lubricating Means for Twister Rings, of which the following is a specification.

My said invention relates to a lubricating device for twister rings, similar in character to that set forth in my application No. 550,- 7149, filed April 8, 1922, its purpose being to provide a simple and etl'ective construction adapted to automatically supply oil to the contacting surfaces of the ring and the traveler for indefinite periods of time without attention on the part of the operator. is is well known, in ordinary practice it is customarv to supply the lubricant to the inner face of the twister ring with the finger and this must be done at relatively frequent intervals, whereas the building of a spool requires a relatively long time. By this method a periodic variation from an excess of lubricant to a deficiency thereof results, which makes for uneven twisting, whereas by employing my device this objection is eliminated and lubrication of a uniform character maintained throughout the entire operation, resulting in a more evenly twisted yarn.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts,

Figure 1 is a perspective view of a twister ring of my improved construction with its traveler thereon, and

Figure 2 a cross section on the dotted line 2+2.

In said drawings the reference character 10 indicates a twister ring and 11 the traveler. both of which devices are-in the main ol the ordinary and well known type.

Surrounding the twister ring is an annular reservoir 12 for containing a lubricant, said reservoir having a filling tube 13 at one side normally closed by a ball 14 held in closed position by a spring 15. A feeder 16 of fibrous material, either wood fiber, or any other appropriate fiber, projects at an angle throu h an aperture into the reservoir 12 with its inner and upper end flush with the inner surface of the twister ring.

. or more of these feeders may be provided as found desirable.

It will be not ed that the feeders extend atan angle from near the bottom of the reservoir to a point substantially in line with or above the upper surface of the oil in the reservoir so that there is no leakage by gravity through said feeder, the oil being fed by capillary attraction to the surface on which the traveler slides.

The top of the oil filling tube or neck is above the upper surface of the oil in the reservoir, to guard against overflow. In filling the reservoir it is only necessary to insert the discharge spout of the oil can in said tube. pressing the ball 14 downward against the spring. When a quantity of the oil or other lubricant has been deposited in the reservoir the can is removed and the filling tube closes automatically.

in operation the traveler moves round and round on the ring with its adjacent surface in more or less contact with the inner surface of the ring. As it passes the end. of the wick 16 itpicks up a minute quantity of the oil and distributes the same to the inner surface of the ring. This continues without any attention whatever on the part of the operator so long as the oil supply remains in the reservoir. I i

Among other advantages, the lubricant reservoir surrounding the ring serves to maintain said ring at a comparatively low temperature during the operation and also prolonging the life of the traveler.

It will be understood, of course, that the reservoir may be made integral with or formed separately and attached to said twister ring and that other obvious modifications may be made in the structure within the scopeof my invention as defined by the claims.

Having thus fully described my said invention. what I claim as new and desire to secure by Letters Patent, 'is:

1. In combination, atwister ring formed with an annular reservoir around its outer surface and with an aperture leading from the inner surface downwardly into said reservoir, and a feeder mounted in said aperture with one end in said reservoir and the other end in line with the inner surface of said twister ring, substantially as set forth.
